T - the type of the value to extract frompublic abstract class AbstractBigDecimalAggregator<T> extends AbstractAggregator<Object,Object,T,Number,BigDecimal>
Number values extracted from
a set of entries in a Map and returns a result in a form of a
BigDecimal value. All the extracted objects will be
treated as BigDecimal, BigInteger or
Java double values.
If the set of entries is empty, a null result is returned.ExternalizableHelper.DecoratedMultiBufferReadBuffer, ExternalizableHelper.DefaultObjectStreamFactory, ExternalizableHelper.FormatAwareCompressor, ExternalizableHelper.IntDecoratedObject, ExternalizableHelper.Shielded, ExternalizableHelper.ShieldedDataOutputStream, ExternalizableHelper.ShieldedInputStream, ExternalizableHelper.ShieldedObjectOutputStream, ExternalizableHelper.ShieldedOutputStream, ExternalizableHelper.SimpleXmlBeanClassCache, ExternalizableHelper.Stats, ExternalizableHelper.XmlBeanClassCacheBase.LoggingWriter, Base.StackFrame| Modifier and Type | Field and Description |

extractor - the extractor that provides a value in the form of
any Java object that is a Numberprotected void init(boolean fFinal)
init in class AbstractAggregator<Object,Object,T,Number,BigDecimal>fFinal - true is passed if the aggregation process that is being
initialized must produce a final aggregation result; this
will only be false if a parallel approach is being used and
the initial (partial) aggregation process is being
initializedprotected Object finalizeResult(boolean fFinal)
If the fFinal parameter is true, the returned object must be the final result of the aggregation; otherwise, the returned object will be treated as a partial result that should be incorporated into the final result.
finalizeResult in class AbstractAggregator<Object,Object,T,Number,BigDecimal>fFinal - true to indicate that the final result of the
aggregation process should be returned; this will only
be false if a parallel approach is being usedpublic static BigDecimal ensureBigDecimal(Number num)
num - a Number object
